To all who/m) it may concern.'

Be it known that I, Or'ro NELSON, a citicago, in thecounty of Cook andState of Illinois, have invented certain new and useful ImprovementsinDiestocks, of which the following is a specification.

4My invention relates to die stocks and has for one of its objects theprovision of a simple and efficient die stock 'for holding a pluralityof diesV capable of being brought quickly and easily into use. l

A further object is the provision of -a die` stock having an openingwith a plurality of dies 'adapted to be brought into registration withthe opening. 'I

7 A urther'objeot is the provision of a die vstock havingiasubstantially centra-l opening with a plurality of dies each adapted tobe brought into registration with said opening and a guidehaving guideopenings adapted to bebrought into registration with theopening in thedie stock. Other objects will appear hereinafter.

An embodiment of my invention is lshown in the accompanyingV drawing,forming a. part of this specification, and in whichv `Fig/1 is a planview of a fdie stock em- Fig. 1; and' Vare mounted.`

bodying my invention; v

Fig. 2 is an edge view of the same; e Fig. 3 is a bottom view of thesame; .'Fig. 4 is a section takenon linea-4 of Figs. 5, 6 and 7 areviews similar to Fig. 4 but showing'diierent forms of portions ot thedie stocks* A l Referring more particularly to the drawing, I haveindicated -a die stock 8 of channel Y Specification of Letters PatentfPatented Jan, 17, 19272, application'mea september 15; 1920. serial No.419,381.

that in this form the Hangers 18 extend over o nto the dies 12 alsoholding them in position in the block 10. In Fig. 5 I have indi! catedthelangesV 18 as/being narrower and not covering the dies 12; The dies12 are held in the block 10 by ianges 14 formed on said block. In Fig; 6I have shown tongues 15 on the'stoOk-S inthe guideway extending intogrooves 16 in the die block 10. In Fig.

7 I have shown the engaging surfaces ofthe lguideway 9.and blo/cl; 10 asbeing curved which would-'prevent .lateral movement'off v' the block outoftheguideway 9. From'this 1t `will be apparent that manyfforms `ofguidewaymay be provided. An essential thing of this invention isproviding. asuitable connection, between the vguideway and block so thatthe block can be slid easily in the guidel way. y l

hev die stock is preferablyV made ina lengthso that the block 10`can beslid so as toY bring each-of'the dies" 12 into operative position inregistration vwith an opening 1,7 i A in the vback of the die stockl.The'block 1()v may be held against longitudinal movement in the guidewayinf'any desirable manner. As a simple means I' have shown a screw 18threaded in a'thickened portion 19 oic 'the guidewayand 'adapted toeXtend through so.k

openings .2O in the block 1() so that theinner end of screw -18- canengagea recess 21 in eachl of the'dies 12." It will be apparent that byunsorewing screw 18 until the block 10 can beslidgalong until the properdie can be broughtopposite the opening 17 and screw.

18 run ythrough opening 20 such VdieV can'be' locked so as to beoperable by the die stock.

Sometimes it is desirable to* Vslightly change the size ofa round soliddie, 'such :as

those indicated. In such cases Irprovide an g opening 22 in one side ofthe guide?) oppo site the screw 18 so that a screw-driver'or otherimplement7 not shown. maybe inserted throughthe opening 22 and-acorresponding opening 24 in block 10 to adjust vthe die 12. Sometimesthef'slotted portion 28 of a die will not be directly opposite itsrecess 21 and in such case's'screw 18 is backed up until the die is freetobe turned varoun'dto bring slot 21 in registration with opening 22. 1The blockflO is provided with an` opening .24 at each die 12 so as tomake cach olf the diesI capable of being adjusted without its beingtaken from thedie stock. y t

It is sometimes desirable to provide a guide on tlie'die stock forfacilitating starting the threads straight. I have, therefore,

indicated a. guide bloclr pivoted at its center on the back of the diestock 8 having a plurality of openings 26 therein corresponding in sizeandnumber to the'siZe and number of dies 12 in block 10.` I have shownsix dies 12 and openings 26, but it Vwill be apparent that the numbermay be changed as desired. `The block 25 is held in yproper position tolbring the openings 26 in registration with opening17 in any` dei sirablemanner, such. as by notches 27 in which a spring-pressed bolt `28 isadapted to engage. It will be apparent that by Withdrawing the springbolt 28 by the handle 29the block 25 can be turned manually to bring anyone of the openings 26 into registration with opening 17 and locked insuch position by simply releasing the han dle 29, permitting thespringbolt28 to automaticallyV move into the `proper'notch 27. As aconvenience I provide pins or screws 30 atthe ends of the .die stock 8to prevent the block 10 from slidingout of the guide- Way whennot heldby the screw 18; Any other desirable means may be used for this purpose.`It will also be apparent that removing one of screws 30 the block 10can be taken out of the guideway and other dies 12 placed inthe block.Of course when Ithe g dies 12 are changed aV block 25`vvith"corre-`sponding openings 26 mustbe put in place y to close the channel.

on the die stock. y Y Y f In Fig. 1` I have indicated a block 31 in thechannel at one end of the die stock 8 It will be apparent l that theblocks 31 are used or'not, as destock a more finished appearance. w y

In Figs.4 and 6 I have indicated grooves 32 under the dies 12 in thestockB to provide. clearance for `chips cut out bythesired,their'onlyfunction being to give the 4 dies in use. `By providinggrooves, such as indicated,` chips which wouldwc'atch and wedge betweenthe die `and stock wouldy either fall out through the groove 32 or elsebe broken so that `they wouldV not interfere `with the free sliding ofthe block in the die stock.` Y
